Everest 428 update rc pipeline

EVEREST-428

UPDATE RC CI

Problem:
rc_rebuild workflow wasn't triggered after the rc_create

Cause:
The rc_create workflow was making a single git push with the new branch, but rc_rebuild is triggered only on the new commits to the existing release branch, so it wasn't triggered.

Solution:
First push the new branch, then push the update commit, which will trigger the rc_rebuild workflow
